2. Kasutusjuhised
2.1 Aritmeetika põhitehted
Perform basic calculations using the number keys and operation keys (+, -, ×, ÷). Vajutage = tulemuse kuvamiseks.
- Täiendus: 5 + 3 = (Tulemus: 8)
- Lahutamine: 10 - 4 = (Tulemus: 6)
- Korrutamine: 7 × 2 = (Tulemus: 14)
- Osakond: 15 ÷ 3 = (Tulemus: 5)
2.2 Teaduslikud funktsioonid
The EL-W531TL offers over 420 scientific functions. Many functions are accessed by pressing the 2. F key followed by the desired function key.
- Trigonomeetrilised funktsioonid: Kasutage patt, cos, tan keys. For inverse functions, press 2. F then the respective key (e.g., 2. F patt for sin-1).
- Logarithms: Kasutage logi (alus 10) ja ln (naturallogaritmi) võtmed.
- Võimud ja juured: Kasutage x² ruudustamiseks √ for square root. For other powers, use yx.
- Murrud: Kasutage ab/c key to enter and calculate fractions.
2.3 Mälufunktsioonid
The calculator includes independent memory (M) and variable memories (A-F, X, Y).
- Store to Memory: Sisestage väärtus ja seejärel vajutage STO followed by the desired memory key (e.g., STO M+ to store to M).
- Recall from Memory: Vajutage RCL followed by the desired memory key.
- Tühjenda mälu: Vajutage M-CLR to clear all memories.
2.4 Režiimi valimine
Vajutage nuppu REŽIIM key to cycle through different calculation modes (e.g., Normal, Stat, Drill). Press CA to change angle units (DEG, RAD, GRAD).

3. Hooldus
3.1 Puhastamine
To clean the calculator, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or spray directly onto the calculator, as this may damage the display or keys.
3.2 Aku vahetamine
When the display becomes dim or calculations are erratic, it is time to replace the battery. Refer to Section 1.1 for battery installation instructions. Always replace with a new LR44 alkaline battery.
3.3 Säilitamine
Hoidke kalkulaatorit jahedas ja kuivas kohas, eemal otsesest päikesevalgusest ja äärmuslikest temperatuuridest. Pikemaajalisel hoiustamisel on soovitatav patarei lekke vältimiseks eemaldada.
4. Veaotsing
| Probleem | Võimalik põhjus | Lahendus |
|---|---|---|
| Ekraan on tühi või tuhm. | Tühi või tühi aku. | Replace the LR44 battery (see Section 1.1). |
| Valed arvutustulemused. | Incorrect mode setting (e.g., RAD instead of DEG). | Check and adjust the angle unit (DEG/RAD/GRAD) using the CA key. Ensure correct input order. |
| Kuvatakse teade "VIGA". | Matemaatiline viga (nt nulliga jagamine, sobimatu sisend). | Review your input and calculation steps. Press ON/C vea kustutamiseks. |
| Calculator is unresponsive. | Ajutine süsteemitõrge. | Vajutage nuppu RESET button (located on the back, requires a thin object like a paperclip). This will clear all memory and settings. |
